Diffusion refers to the movement of solute and solvent molecules from high concentration to their low concentration across the membrane. It depends upon concentration gradient, temperature, pressure, wall permeability etc. Example: movement of ions across plasma membrane.
Osmosis: It specifically refers to the movement of water molecules from low solute concentration medium to high solute concentration medium through the semi permeable membrane. For example. Movement of water in roots from the soil.
Air flow into and out of the lungs is an example of what? Diffusion Osmosis Bulk flow Active Transport Facilitated Diffusion
Discuss the concepts of diffusion and osmosis. Provide examples of how these two forces interact with the body’s cells
give one example of why it would be important to understand the clinical significance of diffusion or osmosis?
Compare and Contrast Diffusion and Osmosis Diffusion Osmosis Is a gradient needed? Direction of movement in relation to the solute) Is a membrane required? Source of energy for movement What is moved
